Why does the Audi A7 only come with a 48-volt mild-hybrid system?

I noticed that the Audi A7 only has a 48-volt mild-hybrid system instead of a full hybrid system like other luxury cars. What is the reason for this and how does it affect performance?

The Audi A7 uses a mild-hybrid system because it provides significant fuel savings at a lower cost compared to a full hybrid system. The 48-volt system utilizes a belt-driven alternator, which allows for smoother stop-start functionality and regenerative braking, providing up to 0.7L/100km in fuel savings.

Don't let the lack of a full hybrid system deter you from considering the Audi A7. The mild-hybrid system still provides a boost in performance, with a quick acceleration from 0-60 mph in 5.2 seconds. Plus, it helps reduce emissions and improves overall efficiency.
